Hey guys,

I went to play with this thing little more..
I am not sure if this means anything but when you push the horn button to blow the horn, I can hear the relay click... Not realy sure if this means anything.. Just thought I would let you know, Trying to get you guys much info as I can..

Thanks again,
Ant...

Refer to the diagram in post #7.

I would think that if you hear the horn relay click when you depress the horn button it shows that the horn relay control coil circuit is intact.

I take it that fuse #21 in the JB keeps blowing when the relay control coil pulls in the relay power contacts (30-87).

To isolate the horn power circuit, pull connector C2 from the JB and see if the fuse still blows. If it does I would think the dead short to ground is in the JB. If it doesn't, the dead short is between connector C2 and the horns.

To see which horn circuit may be shorted to ground, you can (using an Ohmmeter) get a baseline resistance in the horn circuit from connector C2, pin cavity 4, to chassis ground. Record the resistance. If the resistance reads full continuity, or very low resistance there is a short to ground somewhere in the horns or wiring.

Then, remove the horns from their chassis attachment (note that the horns are case grounded) one at a time and see if the resistance changes after each horn is removed. If the resistance changes assume that horn or its wiring has the short. If the resistance doesn't change, the short is between C2/4 and splice S131 (ref diagram).

C2 pinout:



Splice S131. Note that the harness from the splice goes to the right horn then goes over to the left horn. You might want to wiggle these harness runs to see if it makes any change.

Wow, Thanks for this info...

It is fuse 20 that keeps blowing, It is a 15A fuse

As soon as I put the fuse in it blows, Don't have to do anything, It just blows.. I will try what you say to do... Ill let you know what happens,

Thanks a bunch

If it still blows with C2 disconnected, like you said previously, I'd say the problem is in the JB, but who knows at this point.

Keep at it.

Hello All,

I would like to thank you guys for taking the time to help me out with this issue with my horns...

My horns have been fixed ( Couple wires melted together)

The cig lighter is now working as well,
Fixed my trailer light hookup, And third brake light now works.. There was 3 broken wires in the rear where the hatch opens and closes...


Again,

Thanks to all of you...

Ant....
